Cannabis oil refers to any concentrated extract made from cannabis. Cannabis oil can technically come from either hemp or marijuana, since both are varieties of the cannabis plant, but it typically refers to oil made from marijuana, which contains a much higher level of THC than hemp. Cannabis oil that comes from marijuana is highly regulated in the US and across the world. If you live in a state where the use of recreational marijuana or medical marijuana is legal, you can buy it from our marijuana online dispensary, but if you do not live in a state where marijuana is legal, a great alternative is to use CBD oil.
